Characterization of glyphosate resistance in cloned Amaranthus palmeri plants
Glyphosate-resistant Palmer amaranth from Georgia (GA), USA, possesses multiple copies of the gene that encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), the enzyme target site of this herbicide. The cloned plants of glyphosate-resistant and glyphosatesusceptible Palmer amaranth biotypes from Mississippi (MS), USA, and GA were evaluated for glyphosate injury (digital imaging) in leaf...
متن کاملGene amplification confers glyphosate resistance in Amaranthus palmeri.
The herbicide glyphosate became widely used in the United States and other parts of the world after the commercialization of glyphosate-resistant crops. These crops have constitutive overexpression of a glyphosate-insensitive form of the herbicide target site gene, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Increased use of glyphosate over multiple years imposes selective genetic pres...
متن کاملPoster 2001: Generation a hypoallergenic profilin from amaranthus palmeri pollen
Background Amaranthus pollen grains are known to be highly allergenic and a potential cause of respiratory allergic diseases in many countries. Amaranthus palmeri pollen is an important allergenic source in Mexico; however in our country, there is not reported data about the prevalence of these pollens. The first allergenic profilin was identified from birch pollen allergen (Bet v 2) in 1991. M...
متن کاملCytogenetic studies in four cultivated Amaranthus (Amaranthaceae) species
In the present study, the chromosomes numbers were confirmed, 2n = 34 for Amaranthus cruentus Linnaeus, 1759, and 2n = 32 for Amaranthus hypochondriacus Linnaeus, 1753, Amaranthus mantegazzianus Passer, 1864, and Amaranthus caudatus Linnaeus, 1753. The distribution and variability of constitutive heterochromatin were detailed using DAPI-CMA3 banding technique. The position of the nucleolus orga...
متن کاملExtrachromosomal circular DNA-based amplification and transmission of herbicide resistance in crop weed Amaranthus palmeri
Gene amplification has been observed in many bacteria and eukaryotes as a response to various selective pressures, such as antibiotics, cytotoxic drugs, pesticides, herbicides, and other stressful environmental conditions. An increase in gene copy number is often found as extrachromosomal elements that usually contain autonomously replicating extrachromosomal circular DNA molecules (eccDNAs). A...
